Landslides
"The causes of landslides are not a mystery to mankind. Layers of rock and soil such that rain running along a clay or rock layer can create a slippery surface for the weight of the layers above it is a common cause. A rock jumble from previous mountain building, broken or fractured rock easily dislodged. We have stated that the earthquakes man experiences between the periodic passages of Planet X can be considered aftershocks from the last passage, and this is true of landslides also. Mountain building rumples the landscape, so the land is not flat but has steep ravines and hill sides. Older mountain ranges are recognized for their rounded or smoothed appearance, because of frequent landslides distributing the rubble.
"As we approach another passage, another Pole Shift, the pace of landslides has picked up. Why would this be? Plates under pressure will put pressure on regions that contain rumpled hillsides and deep ravines, as these give more readily than strictly flat land, thus act as a weak link. In addition, due to the wobble, the weather has gotten more extreme, with drought and deluge increasing in extremes. Dry ground, suddenly flooded with rainwater needing to seek its level as runoff, will create internal water slides between the rock and soil layers that constitute the rumpled hillsides. Is there an early warning system that mankind could use? The trembles that soil about to slide emits could be detected, yes. These are not earthquakes, and have their own frequency. "

Pakistan Landslides Trigger Migration (Apr 1)
Abdul Rehman, a resident of Suryasar in central Kashmir's Budgam, deserted his house like scores of others after land beneath shook and slid. Dozens like him now live in makeshift shelters like the Khansahib School building as the threat of landslides and caving-in threatens thousands of residents here.
Hundreds of kanals of land in Budgam district, 30 km away from Srinagar, is continuously shifting. "Our house was sinking inch by inch. I bundled my family in a vehicle and left the village," said Rehman.
The district administration has fanned out men and machinery to stop the Laden like tragedy that left 16 dead in house collapse incidents. The villagers have been staying awake during nights since the fateful Monday and feeling of sinking land hasn't stopped.
"We have been complaining about drifting land since March this year. We are getting sleepless nights now," said Ramzan Rather, a local.
Budgam superintendent of police (SP) Fayaz Ahmad Lone grappled the developing landslide situation the whole day on Wednesday. "We are on our toes. We are monitoring the situation and taking necessary steps," said SP Lone.
Budgam's four tehsils of Chrar-e-Sharief, Beerwah, Chadoora and Khansahib is in the grip of high risk landslide situation.
Hundreds of families in these tehsils have shifted to safer locations following sinking and caving-in of karewas (terraced high lands with deep gorges and ravines). The district is spread over 1,370 square km with around 7.3 lakh population.
The areas worst affected were Jawalpora, Brinjan, Hapatnaar, Freshnaar - all precariously perched on karewas facing deep slopes. Some houses were damaged in Lolipora and Rawalpora in the district. Three houses had sunk in Khansahib area.
Agriculture minister and local MLA Ghulam Nabi Lone, who paid whirlwind visit to affected families, said, "Instructions have been made that all major roads should stay open."
Major landslides were also reported from south Kashmir's Shopian district where 45 families were evacuated. A chunk of road was swept by mountain debris on Srinagar-Muzaffarabad in north Kashmir's Uri area.

Popular Cliff Collapses in Southern England (Mar 24)
A cliff-top landslip in South Devon that was so severe it could be seen four miles away has been captured on video.
The coastal path has been closed for safety reasons after tonnes of rubble fell amid fears that sightseers were putting their lives at risk by standing near the unstable cliff.
The incident took place on Sunday evening after the top of the cliff collapsed close to the footpath, between Bantham Beach and Thurlestone Golf Course in the South Hams.
Falmouth Coastguard described the landslip as "substantial".
A spokesman said: "A member of the public spotted it from four miles away so you can imagine how big it was."
The police helicopter assisted officers on the ground by guiding them to the scene and ensuring that no-one was on the coastal path at the time of the collapse.
Inspector Adrian Leisk, of Devon and Cornwall Police said: "This is a very popular route for walkers and thankfully no-one was injured as a result of the incident.
"Last night we made the area safe by putting cordons in place. The stretch of coastal path is now closed until longer-term safety measures have been put in place by Highways.
"We are urging people to avoid the area for the time being for their own safety."
Nobody was hurt in the incident.

Des Moines landslide damages at least one home
DES MOINES, Wash. -- Three homes have been evacuated, and at least one home was damaged following a landslide that struck Des Moines Friday afternoon.
The slide happened just before 4 p.m. along the bluff at 25100 8th Place S., according to Sough King Fire Department officials.
A homeowner noticed the ground moving around 8:30 a.m. on Friday, and occupants were able to get valuables out of their homes before leaving.
The slide is 200-feet wide, and 200-feet tall. South King County deputies say they'll be monitoring the area throughout the night, and more evacuations are possible.
The area was already considered a "sensitive critical area," officials said. There have been smaller slides in the past, but nothing as extreme as Friday's slide.
No injuries were reported.

Landslide Still Moving Slowly in Jackson Since it Started a Year Ago
http://abcnews.go.com/US/wireStory/talks-fix-wyoming-landslide-move...
In this April 19, 2014 file photo a work crew moves a concrete barrier that failed to stop a slow-motion landslide in Jackson, Wyo. The Town of Jackson and property owners are negotiating how they might share what it will cost to stop the slow-moving landslide that for a while threatened to wipe out several homes and businesses last year
Talks to Fix Wyoming Landslide Move Slowly as Ground Itself
The Town of Jackson and property owners continue to negotiate how they might divvy up the multimillion-dollar cost to stop once and for all a slow-moving landslide that for a few weeks last April threatened to wipe out dozens of homes and apartments and a few businesses.
Mediated talks between town officials, homeowners and the Walgreen Co. last fall failed to yield an agreement to fund a project to remove earth from the top of the landslide and build a buttress at the bottom to hold back the creeping mass of earth.
Meanwhile, the ground continues to move at a rate of about half an inch per month. The estimated cost to permanently stabilize just part of the landslide zone: $8 million to $10 million.
--------------------------------------------------------------------------------------------------
The landslide began when a crack opened up beneath a house on a hillside and a few weeks later split the house in two. Officials worried for a time the hill might collapse altogether.
They ordered the evacuation of 42 homes and apartment units April 9. To date, the ranch-style house atop the slide and town pump house near the Walgreen parking lot below have been the only structures destroyed by the event.

Peru Mudslide Desroys 65 Homes, 7 Killed, Emergency Declared (Mar 23)
Peruvian authorities declared a state of emergency in a town hit by an avalanche of mud and rocks on Monday.
“The Government of Peru has declared a 60-day Emergency in the district of Lurigancho-Chosica, following extreme infrastructure destruction caused by severe landslides over the past hours. The emergency declaration is aimed at implementing immediate, necessary measures to respond and restore the areas affected by landslides of mud and rock. Announced by President Ollanta Humala, the initiative followed the formation of Pedregal, Carossio, Rayos de Sol, Quirio, San Antonio, California, La Trinchera, Buenos Aires, La Cantuna, Moyopampa, La Libertad and Mariscal Castilla ravines, located in the said district. According to a supreme decree, published today in the official gazette El Peruano, the adoption of such urgent measures will allow Lima and Lurigancho-Chosica Municipalities to execute response and rehabilitation actions in coordination with the National Institute for Civil Defense (Indeci) and various ministries. Actions include the restoration of basic services and reconstruction of infrastructure, and can be modified in accordance with the needs and security requirements that might arise during the execution.”
A torrent of mud and water sent car-sized boulders crashing through the town of Chosica, 47 km (29 miles) from the capital Lima.
At least seven people were killed and 65 houses destroyed.
Televised images showed police breaking through the wall of one home to recover the bodies of 23-year-old Ana Marino and her 3-year-old son, Stefano. Mother was clutching child.
The country's main east-west highway was blocked and residents are asking for equipment to clear up debris.
Floodwaters smashed through brick walls and carried cars, animals and furniture through Chosica's streets.
The state of emergency was called for 60 days to give powers to the local authorities to re-establish power and water supplies, and initiate a clean-up operation.
Residents in the town have asked the authorities for diggers and heavy equipment.

Check Out What A Landslide did to this Road
http://www.carbuzz.com/news/2015/3/18/Check-Out-What-A-Landslide-Di...
You don't hear it mentioned nearly as much as some other locations, but the small Balkans state of Montenegro has some truly beautiful driving roads. The small picturesque coastal towns and mountainous northern regions offer the same sorts of experiences as Italy or southern France. But those same mountains that are so much fun to drive through can also produce devastating landslides, and here we have some footage of a highway that was completely destroyed by one.The footage was shot by a drone, so it's easy to see the extent of the damage.
We certainly hope it's repaired soon because it looks like it offered some good driving.

Hikers Tumble and Buried Under Cliff Collapse, One Killed (Mar 21)
One person is dead and another suffered critical injuries after a cliff collapsed at Point Reyes National Seashore Saturday evening north of San Francisco.
The two hikers were walking along Bear Valley Trail when they reached the end of the trail at the Arch Rock overlook.
The cliff unexpectedly gave way and they fell an estimated 70 feet below, buried under rubble and rock.
One person was pronounced deceased at the scene and the other was airlifted to Santa Rosa Memorial Hospital.
A fissure appeared at the "tip" of the overlook on Wednesday and park officials immediately put signs up at the trailhead and visitor center to warn visitors they could not hike to the end of the trail.

Cliff Fissure Continues to Grow in Central Texas (Mar 17)
Steve Mellgren walks along a fissure that is opening on the cliff next to his home at Lake Whitney Tuesday, March 17, 2015, in Whitney, Texas. A fissure that caused the cliff to collapse into the Central Texas lake last year appears to be widening and is threatening Mellgren's home.
Last June, a palatial home dangled above Lake Whitney before a demolition crew sent it tumbling into the water.
The same cliff fissure that caused it is still growing.
"It could go into the lake at any time and be a danger to anyone on the water," according to neighbor Steve Mellgren.
Accounts of large rock chunks falling into the lake are common. Authorities have taken steps to inform people of the danger, including installing buoys in the lake to warn boaters to keep away.
But local and federal authorities say they can do little more than monitor threats of a collapse when it occurs on private property.
Tom Hemrick, Hill County's emergency management coordinator, said boaters need to be cautious when they pull close to the cliff, noting that a fisherman several years ago was killed when an outcropping fell on him.
"We're very concerned about the safety along our lake," Hemrick said.
The fissure on Mellgren's land extends down 80 to 90 feet and does not immediately affect his home, Hemrick said, adding that it's difficult to determine whether any collapse is imminent. Complicating the situation are underwater caverns that could destabilize land above.
Mellgren said the U.S. Army Corps of Engineers should be more involved in finding solutions.
The agency acknowledged in a statement that the crack presents a dangerous situation and will work to maximize safety, but added that "private property owners are responsible for correcting the problem."
Robert Webb is still dealing with his own problems after his property collapsed into the water last year only three years after he purchased it. He said his homeowner's policy does not include coverage for "ground movement" and has sued his insurer.
Webb estimates it will cost more than $100,000 to remove the debris and the home's foundation, which still dangles over the cliff. Demolition crews are wary that removing the foundation will trigger another collapse.
Both homeowners say they did not anticipate erosion would be a major issue when they purchased their properties.
"I was assured by everyone there when I bought the property that there had been engineering studies done and everything was safe," Webb said.

Over 1800 Landslides in Bulgaria in One Week (Mar 18)
There have been more than 1800 landslides in various parts of Bulgaria over the past week.
The worst-affected areas are Smolyan, Assenovgrad, Devin and Krichim.
In the Rhodopes, the landslide between Bachkovo and Narechen was blocking the road from Plovdiv to Smolyan for a third day on March 17. Estimates are that about 10 000 tons of rock came down with the landslide.
Cleanup work was continuing at as fast a pace as possible. The route, on the way to the winter resort of Pamporovo, usually serves about 100 000 people daily.
The fallen stones are so large that they cannot be loaded on to trucks. Special equipment has been brought in, two hydraulic hammers to break up the huge rocks.
A landslide between the villages of Gjakova and Kremenik blocked the road near Dupnitsa. There was great danger of a further collapse, Bulgarian National Television said.
A landslide closed one of the most popular tourist routes in the Zlatni Pyasutsi Natural Park near Varna. Collapsing earth and trees destroyed one of the bridges, while large boulders came down from a nearby slope.
The road to the Bulgarian village of Bankya, municipality of Trun, has been blocked by a landslide, reports on March 17 said.
A passenger train travelling from Troyan to Levski derailed on March 17 after hitting a fallen rock in the stretch between the railway stations of Albanitsa and Hlevene.
